Front brakes howling
 

Can i just change pads to lyndal or should i be concerned of bent rotors thanks in advance 21 front dual rotors.

Why are you concerned of possibly "bent" ("warped" is the more appropriate term) rotors? Do you have some performance issue such as pulsating or chattering? If not, the rotors are probably fine.

If you really want to know, it's easy enough to check the rotors. Just put a dial-indicator, or some semi-rigid pointer if you dont have an indicator, up to the rotor and rotate the wheel. The indicator will show you the runout directly. If using a pointer, find the high and low area, and measure the low area with a feeler gauge.

never change pads with new rims will go that direction.

What???

And blue ducks are always cats backwards?

some where along the way I lost the meaning of this thread. so ... what????:icon_crackup:
kroozeabout.

Jack it up & spin the wheel if there is alot of drag in some areas more than others there is a good chance you have warped rotors or if when braking it brakes hard & releases

Where is the interpreter when you need him? ;)

Man......now I need a beer!!!

I put on lyndall pads, and now my brakes squeal.
